Dustin Penner is ready to return from his concussion, but the Anaheim Ducks will be without one, maybe two, players at their game in Columbus on Sunday.

Jakob Silfverberg has a broken hand, the team said, after being slashed in the third period of Friday's victory at the Ottawa Senators, his former team. He will miss four to six weeks.

He has been playing on a line with Teemu Selanne and ranks fourth on the Ducks with seven points.

Third-ranked Mathieu Perreault sprained his wrist in the same game and is day-to-day.

Penner suffered a concussion when Dallas Stars forward Ryan Garbutt left his feet to hit him in a game earlier this week.

Garbutt, who caught Penner in the head and knocked him unconscious briefly, was suspended for five games.

Penner stayed behind from the start of the team's eight-game trip for testing and because he experienced what the team called mild concussion symptoms. But he has been symptom-free for several days and will join the team in Columbus.
